Verfahren zur Herstellung einer thermoakustisch isolierenden
Zwischenbelagmasse
Die Erfindung betrifft ein Verfahren zur Herstellung einer gegen Kälte und Schall isolierenden Zwischenbelagmasse unter Verwendung von Reisschalen, Im wesentlichen besteht das Verfahren darin, dass Reisschalen einer Vorbehandlung unterzogen werden, die aus einer Vibrationssiebung sowie einer Gebläseentstaubung besteht, und hierauf mit einem nicht wässerigen Bindemittel gemischt werden. Die so hergestellte thermoakustisch isolierende Masse ist dazu bestimmt, zwischen ein Bauelement und seiner Verkleidung eingelagert zu werden.
Bauelemente, die aus einer Mischung bestehen aus gerösteten Reisschalen, einem kalziumhaltigen Bindemittel (Kalk und Zement) und einer geringen Menge einer verdünnten Aluminiumsalzlösung, sind bekannt (deutsche Patentschrift Nr. 898272). Geröstete Reisschalen lassen jedoch eine gute Isolierwirkung nicht erzielen. Darüber hinaus wird zur Herstellung dieser bekannten Bauelemente ein Bindemittel verwendet, das mit Wasser angefeuchtet werden muss, ein Umstand, der sich betreffend die Isolationseigenschaften äusserst nachteilig auswirkt. Demgegenüber werden erfindungsgemäss nicht wässerige Bindemittel verwendet, die sich auch sehr leicht mit naturbelassenen Reisschalen mit Hilfe eines einfachen undwilt- schaftlichen Verfahrens mischen lassen.
Auch die gemäss der franz. Patentschrift Nr. l. 087. 518 hergestellten Bauelemente weisen den genannten Nachteil auf, denn auch nach diesem Vorschlag wird mit Wasser befeuchteter Portlandzement als Bindemittel verwendet.
Erfindungsgemäss wird folgendermassen vorgegangen : Die beim Schälen von Reis anfallenden Hülsen, d. s. die Reisschalen, werden einer Vibrationssiebung unterzogen, um sie von ihren organischen Verunreinigungen, wie z. B. vom Reisrückstand, zu befreien. Dieser Vibrationssiebung folgt eine Entstaubung, indem man die Reisschalen der Wirkung eines Luftstromes, z. B. eines Gebläses, aussetzt. Die so behandelten Reisschalen werden dann durch ein Bindemittel, wie z. B. Bitumen, Teer, Asphalt, Kunstharz, od. dgl. vereinigt, um eine Masse für den Zweck eines Zwischenbelages zwischen einem Bauelement und seiner Verkleidung zu bilden, die den Bauteil thermoakustisch isoliert. Die Auswahl des Bindemittels erfolgt entsprechend dem jeweiligen Verwendungszweck.
Beispiel l : Man bringt auf einer Betonfliese eine Schicht aus gesiebten und von seinen Verun- reinigungen befreiten Reisschalen auf, die mit Bitumen vermischt eine Zwischenbelagmasse bilden, die dann noch durch eine Betäfelung belegt oder einen Mörtelüberzug verkleidet wird, der wiederum dazu bestimmt ist, durch Linoleum, durch ein Pflaster aus Vinyl- oder Asphaltplatten oder sonstwelche anderweitige Belegung eine aufgeklebte Decke zu erhalten.
Für Terrassen und Bedachungen mit Betongrundl & ge wird die Zwischenbelagmasse mit einer undurchlässigen Bekleidung versehen, wie z. B. Zink, Kupfer, Aluminium; auf diese kann auch noch ein beandeter Teerbelag aufgebracht werden.
In gewissen Fällen kann die Zwischenbelagmasse auch mit Mörtel verkleidet werden.
Beispiel 2 : Die nach Beispiel 1 aus einer Mischung von Reisschalen und einem Bindemittel hergestellte Masse wird als Zwischenbelag zwischen zwei Bauelemente eingebettet, um dort eine thermoakustische Isolierwand zu bilden.
In den beschriebenen Beispielen kann die Zwischenbelagmasse, statt in zusammenhängender Form,
<Desc/Clms Page number 2>
auch in Form einer Plattenzwischenlage auf das Bauelement aufgebracht werden.
PATENTANSPRUCHES
1. Verfahren zur Herstellung einer thermoakustisch isolierenden Zwischenbelagmasse aus Reisschalen und einem Bindemittel, dadurch gekennzeichnet, dass die Reisschalen einer Vorbehandlung, bestehend aus einerVibrationssiebung und einer Entstaubung durch Gebläse, unterzogen und hierauf mit einem nicht wässerigen Bindemittel gemischt werden.

Process for the production of a thermoacoustic insulating
Intermediate lining compound
The invention relates to a method for the production of an intermediate covering compound which insulates against cold and sound using rice husks. Essentially, the method consists in subjecting rice husks to a pretreatment consisting of vibratory sieving and blower dedusting and then mixing it with a non-aqueous binder will. The thermoacoustic insulating compound produced in this way is intended to be embedded between a component and its cladding.
Construction elements which consist of a mixture of roasted rice husks, a calcium-containing binding agent (lime and cement) and a small amount of a dilute aluminum salt solution are known (German patent specification No. 898272). However, roasted rice husks do not provide a good insulating effect. In addition, a binding agent is used for the production of these known components which has to be moistened with water, a fact which has an extremely disadvantageous effect with regard to the insulation properties. In contrast, non-aqueous binders are used according to the invention, which can also be mixed very easily with natural rice husks with the aid of a simple and economic process.
According to the French Patent No. l. 087.518 construction elements have the disadvantage mentioned, because according to this proposal, portland cement moistened with water is used as a binding agent.
According to the invention, the procedure is as follows: The husks obtained when peeling rice, i. s. the rice husks, are subjected to a vibratory sieving to remove their organic contaminants, such as e.g. B. from the rice residue. This vibration sieving is followed by dedusting, in that the rice husks are exposed to the action of an air stream, e.g. B. a fan, suspends. The rice husks treated in this way are then coated with a binder, such as e.g. B. bitumen, tar, asphalt, synthetic resin, od. The like. Combined to form a mass for the purpose of an intermediate layer between a component and its cladding, which thermoacoustically isolates the component. The selection of the binding agent is made according to the respective purpose.
Example 1: A layer of sifted rice husks that have been freed of its impurities is applied to a concrete tile, mixed with bitumen to form an intermediate layer, which is then covered with paneling or covered with a mortar coating, which in turn is intended to pass through Linoleum, to obtain a glued-on ceiling with a plaster made of vinyl or asphalt slabs or any other type of covering.
For terraces and roofs with a concrete base, the intermediate layer is provided with an impermeable cladding, e.g. B. zinc, copper, aluminum; A tar covering can also be applied to this.
In certain cases, the intermediate layer can also be covered with mortar.
Example 2: The mass produced according to Example 1 from a mixture of rice husks and a binding agent is embedded as an intermediate layer between two structural elements in order to form a thermoacoustic insulating wall there.
In the examples described, the intermediate covering mass, instead of in a coherent form,
<Desc / Clms Page number 2>
can also be applied to the component in the form of an intermediate plate layer.

A method for producing a thermoacoustically insulating intermediate covering mass from rice husks and a binding agent, characterized in that the rice husks are subjected to a pretreatment consisting of vibration screening and dedusting by means of a fan and then mixed with a non-aqueous binding agent.
